5. (Unsure. It is unlikely the Legendary Hero Summoning Event or any focuses scheduled after that were added. Based on the timing, there is a decent chance it is a rerun of Performing Arts. Otherwise, we could finally get the return of Grand Hero Battle banners, or perhaps there will be a "free pick" banner for the Múspell group similar to CYL? Or just something else that was completely omitted from the calendar.)
